I 5 arrangement enabling this result to he attained is applicable with advantage to a va- "riety of technical purposes'for instance, where the carriage or. slide supports a tool which might then while beingrevolv'ed be :0 moved nearer to or farther from its axis of revolution. ,This, it the translatory movement of the tool-carrying slide be properly controlled, results in an arrangementfor plane-turning or facing'with the workpiece simply secured on the bench or bed of the machine-tool an arran ementthe advantage whereof over that'in which the tool is fastened to the plate is that itenahles the tedious operations of centering, truing, 0 and balancing-to be dispensed with; Among the other possible applications of such acon-' trivance the case of a slide carrying a crankpin may be instanced, admitting of the stroke of .the machinesay, a pump, a slotting or 5 planing machine, a cycle, &c.being varied while the machine is in operation.

In adopting any of the means hitherto dcvised for solving the problem above stated it has been necessaryin order to shift'the slide 6 in either direction toretardoraccelerate the rotary inoiionof a controlling wheel, or the speed of either of two rotating controllingr; heels had to he reduced; but in neither case is it possible to impart to the slide a more 5 went limited accurately at will or aeonstant translatorymovement standing in a prede- Lei-mined relation to its number of revolulions. Now this important requirement is met by the present invention in the manner 50. hereinafter described.

' With the operating mechanism mounted ponents in the dilferent modiiications illus upon the plate which carries theslide and serving to feed along such slide a controllingwlieel concentric with the axis of revolution of the slide-carrying plate is connected in 5 5, such a way that as long as it is prevented from turning the-slide or carriage though it may rev'olve cannot at the same time receive a feeding or sliding movement from the said mechanism, whereas whenever the said controlling-wheel is turned the slide will thereby be caused to travel along for a corresponding distance. It will be understood that the retary movement ofthis controlling-Wheel may: be exactly measured and regulated at will; To prevent the controlling-wheel from rotating with the plate while the slide is not required to be fed along, a screw or worm may be fitted Within the mechanism for operating the,controlling-wheel, or a brake or locking 7o device capable of lbeing readily released maybe provided, or it may suffice to insure adequate friction.

In the accompanying drawings, Figural is an axial section of a slide earrying plate con- 7 5 structed in accordancewith this invention and of which Fig/2 is a plan. Fig. 3 is an elevation of a plate of a similar form of construction. Fig. 3 is a transverse section of substantially the same plate as shown in Fig. ,80 3,- but having modified gearing means. Fig.

at is an axial section showing a third form of construction of the device, Figs. and 6 being respectively a front elevation and a plan thereof. Fig. 7 is an axial section of a similar plate. Fig. 8 is an axial section of afifth modification of the said plate, Fig. 9 being a front view, and Fig. 10 a plan, of such plate. Fig. 11 is a side View of a similar form of construction of the improved apparatus. Fig. 12 is an axial section of a seventh modification of the invention, while Fig. 13 is a corresponding front elevation, and Fig'll a plan, of the same. y

In the several modifications represented in the drawings certain parts which though different in outward appearance serve for fulfilling similar functions are designated by like letters of reference, but having different ex-' trat'ed.

\Vith the exception of Fig. imvhich shows a crank-disk, it is assumed that a face-plate" fitted 'witn-a sliding tool-holder has to be dealt with and that such plate forms a selfcontained device adapted to be screwed bodily onto the spindle of an existing lathe or of a shaping,undercutting, drilling, or like machine. lVhen the said face-plate instead of being, as here shown, a removable and exchangeable piece is intended to form the' main part of a machine-tool of novel type, this will afiord increasedconveniencefor the accommodationof the diverse parts of.

machinery. In the illustrations of the several forms of apparatus here given it issupposed that two slides are adapted to travel in opposite directions upon the same diameter of the plate, except in Fig. 7, where a single carriage is shown. It will be understood that the number of the slides may easily be in creased with only structural modifications of the examples here given. The formsof con struction which the drawings illustrate may be divided into two sets or groups, of which 11 e one comprised in Figs. 1 to 7 will be described first. In all the arrangements belonging to this group there are provided two planet-wheels adapted to revolve at a-like angular speed, Whether they be mounted coaxially or whether their respective-axes be" placed at an invariable distance from'each other, one of such wheels being in gear with a toothed rim, which forms part of the controlling-wheel'and being connected with the slide in such a manner that by turning the controlling-wheel the slide may be fedalong, while the other planet-wheel engages with a second toothed rimrlikewise concentric with the axis of the plate, but stationary and is so connected with the slide-carrying plate that such plate whenever it turns causes the said planet-wheel to revolve.

In the GXQUHPIGSIIOWD in Figs. 1 and 2 two slides or carriages a are supposed to be mounted upon the same plate I). The two planet-wheels c and d are connected with the two slides by means of a spindle e, diametrically arranged on the back of theface-plate I), and by means of a bush f, coaxial with the said spindle, by'the longitudinal slots g, of which bush the nuts h of the spindle e are guided. Over the bush f two sleevesi are' passed, these being screwed or otherwise suitably secured to the nuts h. An annular collar 11, provided on each of the sleeves 2', engages in the slot or groove of one of two blocks is, rigidly connected with the slidesa,

so that whenever the spindle-e is rotated in relation to the bushf and the nuts hare dis placed in consequence the'slides a are thereby xnoved radially. The spindle e is by the planet bevel-wheel e geared with the bevelwheel on, secured tothe controlling-wheel Z, while the bush f engages with the stationary toothed rim on through the medium of the planet bevel-wheel d. The dimensions of the wheels 'are so determined that while the control'l in g -whecll is at rest the two planet-wheels wheels (1 c..

other gear -wheels adapted .for crossing shaftssay helical wheels, as shown in Fig. The controllinge and d, and also, consequently, the spindle e and bush f, turn about their common axis at i an equal angular speed, so that the nuts h do not move radially, whereas they will beginso to move the moment a difference in the rotation of the wheels 0 and d is brought about by a rotary movement of the controllingwheel Z. The face-plate b is represented as being screwed onto the spindle of the latheby means of its boss U. The controllingwheel'l is mounted not directly upon the-boss U of the face-plate b, but upon a sleeve 0, ro- .tatable on such boss and fitted with an arm 0,

engaging with thelathe-bed slot, such sleeve 0 at the same time carrying the stationary toothed rim n. In the arm oa bearing is provided for-the shaft 1), which shaft for operating the controlling-wheel Z gears, by means of a worm p, into the teeth of the worm-wheel or rim q,-forming part of the controlling- 3may be substituted. wheel is here supposed to be driven not bya worm and. worm-wheel, as in Figs. '1 and 2,

but through bevel-wheels p and q, a lock or brake device controllable from the crankhandle being provided,-but not shown, to secure the controlling-wheel in the position of rest.

In the form of apparatus represented in Figs. 4 to 6 the planet-wheel e gearing with the toothed rim m of the controlling-wheel Z, is arranged coaxially with and rotatably in relationto the planet-wheel d, which has the same size as the planet-wheel c and gears withthe stationary toothedrim ht. The shaft of the planet-wheels'c and d has its hearings in an arm 7', revoluble on the boss 12 0f the face-plate. To turn this arm, a spur-wheel f rigidly connected to the planet-wheel d, but of larger size, gears with a toothed rim g, secured'to the boss 12' of the plate I). A spurwheel e 'of the same size as the wheel fis ITO rigidly connected to the planet-wheel and m gears. with atoOthedTim' h, loosely mounted upon the boss b of the faceplate. The said wheels have such proportions that the spurwheel 6 imparts to the toothed rim it while the controlling-wheell remains at rest a rotary movement, which both as regards direction and angular speed 'is identicakwith that performed by the plateb. Each rotary movement of the controlling-wheel, however, will result in making thetoothed rim h either lag behind or take the lead of the said plate I), and consequently will involve a translator-y 632,230 l p s movement of the two slides a the racks k of which gear with the toothed rim h.

Fig. 7 shows a form of plate differing from the plate just described in that the rim 71- instead of engaging a rack secured to the slide is rigidly connected to a spirally-grooved disk i with the thread of which engage the teeth 717 of the slide a Another typical form in which this invention may be carried out is exemplified by Figs. 8 to 10, 11, and 12 to 14. In the arrangements of this class the controlling-wheel cannot be mounted directly upon the boss of the faceplate, as it would have been feasible in the first group of examples, but must neces sarily be carried by a sleeve, which is prevented from turning with the said face-plate.

Upon this sleeve the controlling-wheel is fitted by means of a screw-thread, so that with its rotary motion an axial displacement is connected, which may be made serviceable in a variety of ways for feeding along the slide.

In the example shownin Figs. 8 to 10 this resuit is attained by giving the boss of the controlling-wheel l the shape of a cylindrical rack m, the pinions h", which are in gear therewith and are supported by the face-plate, being each mounted upon a shaft which also carries a toothed sector i engaging with the rack k of one of the slides a. The sleeve 0 in the example here represented is supposed to be retained in place, not, as in the arrangements previously described, by an arm eugaging with the slot of the lathe, but by a screw, mounted in the head-stock of the lathe. The controlling-wheel has no'special driving mechanism provided for it, but is fitted with handles, it being assumed that its screw-thread fits that of the sleeve 0 tightly enough to prevent the said controlling-wheel when the toothed wheels it turn from being carried around with them owing to their frictional contact with the cylindrical rack m.

Fig. 11 shows an arrangement which is substantially the same as that represented in Figs. 8 to 10, the only difference being that the face-plate disk b is not screwed upon the spindle or mandrel of the lathe, butis clamped onto a boring-rod 8, while the sleeve 0 as in the first group of examples, is retained in position by the arm 0.

In the arrangement shown in Figs. 12 to 14: there are substituted for the cylindrical rack m of the last preceding example separate racks m guided in slots of the face-plate b and coupled with the controllingwheel, so as to follow the axial movement of this wheel. Instead of with handles the controllingwheel is provided with a special operating mechanism, consisting of a toothed rim g which instead of gearing with a worm 19 direct gears with a spur-wheel p rigidly connected with the worm-wheel p \Vhat I claim, and desire to secure by Letters Patent of the United States, is
